A router is the heart of your network, so it deserves to
be chosen with care. Any router will share your Internet connection between
your computers and other network devices (smartphones, tablets, etc.), but
better models offer features that will improve your network and your
performance. Whether you are looking for a professional or consumer router,
here are the eight most important features to look for.
Wi-Fi
access point
Most consumer and SME
routers have an integrated Wi-Fi access point (AP) to provide wireless network
connections to PCs and other devices with Wi-Fi adapters. Additional access to
extend the range of the router. A standalone access point can also add wireless
functionality to a wired router. Different wireless standards are used, the
IEEE 802.11a, 802.11b, and 802.11g standards are considered legacy standards.
The IEEE 802.11n is the latest ratified standard and 802.11ac is in
"draft" mode and final ratification is scheduled for the end of the
year or early next year. There is a small possibility that devices based on
this standard are not compatible with the final standard, but most people in
the industry consider this event very unlikely.
Wireless routers work
on one of two frequency bands: 2.4 GHz or 5 GHz. The 2.4 GHz band provides only
three non-overlapping channels, so it can get congested very quickly. There are
23 non-overlapping channels available on the 5 GHz frequency band, so much less
interference will occur when operating a network. Routers and access points
capable of operating in both the 2.4 and 5 GHz frequency bands are described as
"dual-band" products.
No 10. We are cold to
get the discrete Intel
If you buy a router
today, choose a model based on 802.11n or on the provisional version of
802.11ac.
Guest
Wi-Fi access
Some consumer routers
include what providers generally call wireless guest access. This feature
allows you to broadcast a separate wireless network name (SSID) with security
settings other than the primary wireless network. Since the two networks are
practically separate, guests cannot see traffic or access computers on the main
network. This allows you to easily offer visitors, contractors, and even public
wireless access while keeping your private network safe.
Virtual
LANs and multiple SSIDs
Many Business Router goes further by
offering a simple wireless guest function. They will allow you to create
multiple separate custom networks using the so-called Virtual LAN (VLAN). They
will also allow multiple SSIDs to offer virtual wireless networks.
For example, you can create
a management VLAN where you can share sensitive company information, a VLAN for
regular employees to share files, and a VLAN for guests with limited Internet
access. You can then assign the router's Ethernet ports to the desired VLAN and
transmit a separate SSID for each VLAN. Or, if you are using 802.1X
authentication, you can assign users to a VLAN and they will be dynamically
connected to their VLAN when they connect to an Ethernet port or when they
connect to a single SSID.
VPN
Server and Client
Some enterprise-level
routers include a virtual private network (VPN) server and/or client. Many
providers market these devices as a VPN router. An integrated VPN service
allows users to securely access the network and files while traveling or
working from home. With an integrated VPN client, you can connect one router to
another router with a VPN server to securely connect two networks together on
the Internet, allowing you to share resources and network files between two or
more physical locations.
USB
port for printers or drives
Some consumer and
professional routers include a USB port to share a USB printer or external
drive with the network. This is useful if you do not already have a
network-ready a printer that can be used by all network users or network-attached
storage (NAS) for centralized file storage and sharing.
Malware
and spam protection
Professional routers
that include additional security features are commonly known as Unified Threat
Management (UTM) gateways. They usually include antivirus, antispam and content
filtering to block unsafe or inappropriate websites and emails. Although
individual computers must always have an antivirus tool installed, a UTM the
gateway can help detect malware before it reaches individual computers,
offering double protection. Sometimes UTM gateways provide intrusion detection
and prevention functionality to help block further threats on the local network
or the Internet.
Dual
or backup WAN port (or 4G support)
A Commercial Router that includes two WAN
/ Internet ports (or 4G support) offers another Internet connection for backup
or load balancing. Connect the router to two cable or DSL lines from different
service providers or connect a 4G USB adapter and you will have a backup
connection in case of failure. Some routers allow you to increase Internet
bandwidth by using both Internet connections simultaneously. This is commonly
known as load balancing.
RADIUS
Server
Some professional
routers include a built-in Remote Authentication Dial-In User Service (RADIUS)
server, which allows 802.1X authentication so you can use WPA or WPA2 corporate
security mode for Wi-Fi. the pre-partition key (PSK) provided by traditional Router Services such as WPA (Wi-Fi
Protected Access). Using RADIUS, you can assign each user a unique username and
password, then change or revoke access in case a user leaves or loses its Wi-Fi
device.
